Cultivation zone (below ~1,800 m)
The mountain’s lower slopes are farmland, not wilderness — coffee and banana plantations worked by local Chagga communities. Most climbs start above this zone, at the park gates.
Rainforest zone (~1,800–2,800 m)
Warm and wet — daytime highs of 21–32°C, dropping to 4–15°C at night, with frequent mist and rain.
- Flora: Tall camphorwood and olive trees, with a dense understory of ferns, orchids, and mosses.
- Fauna: This is the richest zone for wildlife on the mountain. The black-and-white colobus monkey — recognizable by its long, flowing white tail — is the signature species here, alongside blue monkeys and olive baboons. Elephants, buffalo, leopards, serval cats, civets, and bush pigs all pass through, though most are rarely seen by trekkers.
Heather-moorland zone (~2,800–4,000 m)
Trees give way to open moorland — daytime temperatures of 10–27°C, dropping to as low as -1°C at night.
- Flora: Two plants define this zone: the giant lobelia (Lobelia deckenii) and the giant groundsel (Dendrosenecio kilimanjari) — tall, strange-looking plants found almost nowhere else.
- Fauna: The eland, Africa’s largest antelope, occasionally ranges this high, along with duiker. In 1962, a pack of African wild dogs was spotted as high as the Shira Plateau — a rare event, not something to expect on a climb.
Alpine desert zone (~4,000–5,000 m)
A stark, dry landscape with extreme swings between day and night temperatures.
- Flora: Sparse — a few hardy everlastings and yellow daisies.
- Fauna: Almost nothing lives at this altitude. The zone’s strangest claim to fame: in 1926, a frozen leopard carcass was discovered near the summit — the same one that likely inspired Ernest Hemingway’s short story The Snows of Kilimanjaro.
Arctic zone (above ~5,000 m)
The summit zone — bare rock and ice, with intense solar radiation by day and severe cold at night.
- Flora: Virtually none. The only survivors are lichens, which grow at roughly 0.5 mm per year.
- Fauna: None.
